Bulko is a platform for cold email outreach with AI-powered content rotation, response filtering, and deliverability control. We help teams communicate with clients from the first email to closing a deal.
Bulko
What we do
Deliverability
SPF/DKIM/DMARC support, SMTP rotation, provider limit control, and automatic bounce handling.
AI automation
Subject and email body generation via Gemini/OpenAI, {word1|word2} rotation, classification of replies into positive/negative/auto-reply.
Analytics
Open/click tracking, campaign reports, follow-ups for non-responders, A/B testing at the subject and content level.
Principles
No long-term contracts
Pay-as-you-go: buy a pack of emails and use it whenever you need. No subscriptions or hidden limits.
Two sending formats.
Campaign Platform uses Bulko's ready-to-use infrastructure. SMTP Access provides separate relay credentials for your application.
AI filter
Built-in protection against phishing/malware sending: Gemini checks email content before sending.
REST API
Bearer API for campaigns, imports, statistics, replies, and balances. Webhooks are in development.
